She was concerned about her baby after the fall and called an ambulance to take her to Thayer Memorial Hospital in Waterville.

“We believe she and the baby are OK,” Trafton said.

When police went to the home, the woman already had gone to the hospital, and Spaulding denied that he had pushed her off the stairs.

Officials are continuing to investigate the incident, and more charges may be pending, Trafton said.

Spaulding was charged with elevated aggravated assault against a pregnant woman and violation of his conditions of release from a prior arrest.

He remained in custody at Waldo County Jail in Belfast on Tuesday afternoon, and an official there said bail was set at $5,000 for the charge of assault. However, because Spaulding also was charged with violation of his conditions of release, no bail is being allowed.
